Future perspectives on solid-state storage

Solid-state batteries are viewed by many as the most promising technology to succeed today’s lithium-ion technologies in many energy storage applications. But there are still plenty of barriers to large-scale use of this type of battery. An international team of scientists has reviewed recent progress with the technology, and examined the form and chemistry that commercial solid-state batteries might take.

Whether degradation and performance loss, reliance on expensive materials or risk of fire, today’s lithium-ion battery technologies come with a host of areas to improve on.

Solid-state batteries potentially tick all of these boxes and could offer much higher density at the same time. And the technology has certainly grabbed the energy industry’s attention, with major battery players such as CATL, Ganfeng Lithium, Samsung and Mercedes working to develop solid-state battery concepts for various applications.

In a new paper, Designing solid-state electrolytes for safe, energy-dense batteries – published in Nature Reviews: Materials – scientists from Cornell University and China’s Tsinghua University review recent progress with various iterations of solid-state technology and the challenges still remaining for the production of practical solid-state batteries of any chemistry.

New challenges

The group notes that while dendrite formation at the lithium-metal anode has historically been one of the biggest hurdles, recent developments have proved reliable in avoiding this, allowing researchers to focus on other areas.
